摘要
Microstructure evolution and crystallization kinetics of a melt-spun (Fe0.05Co0.95)(89)Zr7B4 alloy are examined by several transmission electron microscopy techniques. The as-spun alloy shows a high density (similar to 10(24) m(-3)) of 2-4 nm diameter body-centered cubic(Co,Fe) grains embedded in an amorphous matrix, which act as nuclei for growth during primary crystallization. Phase formation and defect densities are presented for primary crystallized and in situ heated samples. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
